Abstract: A superoxide dismutase from Allium Sativum plasma has been isolat ed and purified by the heat treatment.sedimentation with isoelectric point and ch romatograph on DEAE-cellulose,and it’s property was studied.The study shows t hat:the enzymatic activityis stable within the temperature 40~60℃ and pH 4 ~ 9.And the enzyme is sensitive to KCN and H2O2,the absorption apex exhibits a t 2 58nm in ultraviolet spectrum and at 680nm in visible spectra,the facts indi cate that the enzyme is copper/zinc SOD.

Key words: allium sativum plasma, superoxide dismutase, property
